Looping constructs

for x in iter will take elements from the iterator iter and bind them to the name x.
It will do whatever is in its body with each x from iter.

for x in range(1, 4):
    print(x, end=' ')
else:
    print()

The above code prints 1 2 3 4.

Python loops can also have an else clause, which will execute if and only if the loop did not encounter a break statement.

while True:
    print("Executed once")
    break
else:
    print("This will never execute")

This prints Executed once.

Python also has a continue keyword for its loops.

for x in [1, 2, 3]:
    if x % 2 == 0:
        continue
    print(x, end=' ')
else:
    print()

The output from this one is 1 3.
